`REFRIGERATOR OR BUTTER-COOLER.

SPECIFICATION- forming part of Letters fatent No. 279,296, dated June 12, 18.83;

Application filed February 26, 1883. (No uiodeLt4 To @ZZ whom it may con/cern.:

Beit known that I, ORRIN Miro XVHITMAN, of Boston, in the county of Suffolk, ofthe Comnionwealth of Massachusetts, have invented a new and useful Improvement in Retrigerators or Butter-Coolers5 a-nd I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of whichy Figure 1 is a front elevation, Fig. 2` a transverse section, and Fig. 3 a longitudinal section, of a refrigerator or butter-cooler of my improved kind, this latter section sl'iowiug the rear parts of its rotary cells.

The nature of my invention is duly set forth in vthe claim hereinafter presented.

In such drawings, A denotes a box, chest, or ice-holder, having in its front one or more openings, a., each of which is for reception of a revoluble cell, B, composed of a rectangular frame, b, a disk, c, a semi-disk, d, and a glass pane, e, arranged substantially as represented. The frame b fits the opening a, and is pivoted therein, so as to be revoluble horizontally, the pivots shown at ff being at the iniddles of the two horizontal edges ofthe said frame. From the lowermost of the two pivots of each frame a crank, g, extends, as sh own, and is connected at its wrist to 011e end ot' a spiral spring, l1, whose other end is either A fixed tothe wrist of another of the cranks or to the case A. From the case there is extended a stop, i, for the frame to bring up against when the revoluble cell is open or closed-that is, in either of its two extreme positions. In some cases the cell may be constructed as shown at Bviz., of a frame, b', a semicircular disk, c', and a glass pane, e, arranged as represented. In this latter construction the pane is a ilat sheet of glass 5 but in the cell B such pane is a curved sheet of glass semicireular in transverse section. The cell is revoluble in either direction one hundred and eighty degrees, the frame being provided with notches In. a to receive the stop, in order to admit ofthe frame being so revolved, and stopped when either side of it is iiush with the outer face of the ice-holder.

On a mass or a series of lumps of butter being placed in a cell, B, the latter can be revolved so as to carry the mass or lumps within the ice-holder or out thereof, as occasion 'may require, the said ice-holder being to contain ice for keeping cool the air within it.

lt will be seen that when a cell is either open or closed, as mentioned, it closes the opening u. in which it is placed, so that little, it' any, cool air can escape from the ioe-holder or warm air enter it; also, that we have by the spring and crank and stop fi. of each cell a ready means of holding the cell in either a closed or open position-that is, either turned outward or inward relatively to the ice-holder, such spring and crank readily admitting ot' the cell being so revolved.

I Claimy The combination of the ice-holder provided with one or more cell-receiving openings and a stop to each, Vas described, with a revoluble cell, essentially as explained, arranged in and pivoted to the opening, and provided with a crank and spring, all being adapted and to operate substantially as represented.

ORB-IN MILO VHITMAN.
